gl function was not loaded

I tried to debug this issue, but I'm not sure whats the problem. I get the following error when running with cargo run --release:

Hi, I was unable to reproduce this.

Out of curiosity, what platform are you on? My hunch is that the OpenGL (hardware?) installed on your machine might be an unsupported version.
